Subject: [PATCH 3/8] xtensa: switch to generic version of pte allocation
Date: Sat, 27 Jun 2020 14:34:48 +0000 [thread overview]
Message-ID: <20200627143453.31835-4-rppt@kernel.org> (raw)
In-Reply-To: <20200627143453.31835-1-rppt@kernel.org>
From: Mike Rapoport <rppt@linux.ibm.com>
xtensa clears PTEs during allocation of the page tables and pte_clear()
sets the PTE to a non-zero value. Splitting ptes_clear() helper out of
pte_alloc_one() and pte_alloc_one_kernel() allows reuse of base generic
allocation methods (__pte_alloc_one() and __pte_alloc_one_kernel()) and the
common GFP mask for page table allocations.
The pte_free() and pte_free_kernel() implementations on xtensa are
identical to the generic ones and can be dropped.

Subject: [PATCH 3/8] xtensa: switch to generic version of pte allocation
Date: Sat, 27 Jun 2020 17:34:48 +0300 [thread overview]
Message-ID: <20200627143453.31835-4-rppt@kernel.org> (raw)
In-Reply-To: <20200627143453.31835-1-rppt@kernel.org>
From: Mike Rapoport <rppt@linux.ibm.com>
xtensa clears PTEs during allocation of the page tables and pte_clear()
sets the PTE to a non-zero value. Splitting ptes_clear() helper out of
pte_alloc_one() and pte_alloc_one_kernel() allows reuse of base generic
allocation methods (__pte_alloc_one() and __pte_alloc_one_kernel()) and the
common GFP mask for page table allocations.
The pte_free() and pte_free_kernel() implementations on xtensa are
identical to the generic ones and can be dropped.
